Pomiar prądów fazowych silnika z magnesami trwałymi

The method of PMSM phase current measurement is presented in the paper. The shape of the chase current includes a lot of glitches. The software method of eliminating these glitches is necessary. Simple averaging of the block of probes is applied. Experimental results prove that the averaging is a key point for further calculations. Moreover, the PMSM motor operates more stable. This means a smaller difference between the set point and the actual speed during both no-load and load operation.
